Its program memory is 64 KB of FRAM — ferroelectric RAM that holds data without power, writes at bus speed with no erase cycle, and draws near-zero standby current. That makes it a direct fit for metering, medical sensor endpoints, and any application where the firmware needs to log data or update parameters frequently without wearing out Flash sectors.
It is active — Texas Instruments lists it as current production with no end-of-life notice.
Yes — the connectivity block includes I²C, along with SPI, UART/USART, and IrDA.
Within the MSP430FR6822x family, devices with the same 64-VQFN package and 52 I/O count are pin-compatible across the FRAM density options. The MSP430FR68221IRGCR sits at the 64 KB FRAM tier; a higher-density sibling (e.g., 128 KB FRAM) uses the same footprint and peripheral set, making a drop-in upgrade possible without a board spin.
